A session time-out lock is a temporary action taken when a user stops work and moves away from the immediate physical vicinity of the information system but does not log out because of the temporary nature of the absence. Rather than relying on the user to manually lock their application session prior to vacating the vicinity, applications need to be able to identify when a user's application session has idled and take action to initiate the session lock. The session lock is implemented at the point where session activity can be determined and/or controlled. This is typically at the operating system level and results in a system lock, but it may be at the application level, where the application interface window is secured instead. The organization defines the period of inactivity that shall pass before a session lock is initiated, so this must be configurable.
Checks: C-24911r430774_chk

Review the SharePoint server configuration to ensure a session lock occurs after 15 minutes of inactivity. In SharePoint Central Administration, click Application Management. On the Application Management page, in the Web Applications section, click Manage web applications. Verify that each web application meets this requirement. - Select the web application. - Select General Settings >> General Settings. - Navigate to the Web Page Security Validation section. - Verify that the Security Validation is "On" and set to expire after 15 minutes or less. If Security Validation is "Off" or if the default time-out period is not set to 15 minutes or less for any of the web applications, this is a finding.

Security attributes are abstractions representing the basic properties or characteristics of an entity (e.g., subjects and objects) with respect to safeguarding information. These attributes are typically associated with internal data structures (e.g., records, buffers, files) within the information system and are used to enable the implementation of access control and flow control policies, reflect special dissemination, handling or distribution instructions, or support other aspects of the information security policy. One example includes marking data as classified or FOUO. These security attributes may be assigned manually or during data processing, but, either way, it is imperative these assignments are maintained while the data is in storage. If the security attributes are lost when the data is stored, there is the risk of a data compromise.
Checks: C-24912r430777_chk

Review the SharePoint server to ensure the use of security attributes with stored information is maintained. Click Site Settings. Under the Web Designer Galleries menu, click Site Content Types. Define a set of Content Types that can hold "security attributes", e.g., FOUO, etc. For each required Content Type, under "Change Content Type Column" ensure "Required (Must contain information) is selected. Otherwise, this is a finding.

Fix: F-24900r430778_fix

Configure the SharePoint server to maintain and support the use of security attributes with stored information. From the Site Collection Settings menu: Add a column to Content Types that can hold "security attributes", e.g., FOUO, etc., and "prompt the user to enter as metadata or properties to collect when documents of this content type are added to SharePoint."

Remote access is any access to an organizational information system by a user (or an information system) communicating through an external, non-organization-controlled network (e.g., the Internet). Examples of remote access methods include dial-up, broadband, and wireless. Remote network access is accomplished by leveraging common communication protocols and establishing a remote connection. These connections will typically occur over either the public Internet or the Public Switched Telephone Network (PSTN). Since neither of these Internetworking mechanisms are private nor secure, if cryptography is not used, then the session data traversing the remote connection could be intercepted and compromised. Cryptography provides a means to secure the remote connection to prevent unauthorized access to the data traversing the remote access connection, thereby providing a degree of confidentiality. The encryption strength of mechanism is selected based on the security categorization of the information traversing the remote connection.
Checks: C-24913r430780_chk

Review the SharePoint server configuration to ensure approved cryptography is being utilized to protect the confidentiality of remote access sessions. Navigate to Central Administration. Under “System Settings”, click “Configure Alternate Access mappings”. Review the “Public URL for zone” column values. If any URL does not begin with “https”, this is a finding.

Remote access is any access to an organizational information system by a user (or an information system) communicating through an external, non-organization-controlled network (e.g., the Internet). Examples of remote access methods include dial-up, broadband, and wireless. Remote network and system access is accomplished by leveraging common communication protocols to establish a remote connection. These connections will typically originate over either the public Internet or the Public Switched Telephone Network (PSTN). Neither of these Internetworking mechanisms is private or secure, and they do not, by default, restrict access to networked resources once connectivity is established. Numerous best practices are employed to protect remote connections, such as utilizing encryption to protect data sessions and firewalls to restrict and control network connectivity. In addition to these protections, auditing must also be utilized in order to track system activity, assist in diagnosing system issues and provide evidence needed for forensic investigations post security incident. When organizations define security-related application functions or security-related application information, it is incumbent upon the application providing access to that data to ensure auditing of remote connectivity to those resources occurs in support of organizational requirements. Remote access to security functions (e.g., user management, audit log management, etc.) and security-relevant information requires the activity be audited by the organization. Any application providing remote access must support organizational requirements to audit access or organization-defined security functions and security-relevant information.

Note: If no unsanctioned information is transferred, and has been documented by the Data Owner, IRM is not required. This requirement is Not Applicable. Review the SharePoint server configuration to ensure remote sessions for accessing security functions and security-relevant information are audited. Verify that SharePoint audit settings are configured at the site collection level in accordance with your system security plan. To verify audit settings at the site collection level for each site collection level subject to auditing per the SSP: Click Settings >> Site settings. If not at the root of your site collection, under Site Collection Administration, click Go to top level site settings. (Note: The Site Collection Administration section will not be available if you do not have the necessary permissions) On the Site Settings page, under Site Collection Administration, click Site collection audit settings. On the Configure Audit Settings page verify the events that are required to audit are selected, and then click OK. If nothing is selected, or the selected criteria do not match the SSP, this is a finding.

Information flow control regulates where information is allowed to travel within an information system and between information systems (as opposed to who is allowed to access the information) and without explicit regard to subsequent accesses to that information. From an application perspective, flow control is established once application data flow modeling has been completed. Data flow modeling can be described as the process of identifying, modeling, and documenting how data moves around an information system. Data flow modeling examines processes (activities that transform data from one form to another), data stores (the holding areas for data), external entities (what sends data into a system or receives data from a system), and data flows (routes by which data can flow). Once the application data flows have been identified, corresponding flow controls can be applied at the appropriate points. A few examples of flow control restrictions include the following: keeping export-controlled information from being transmitted in the clear to the Internet and blocking information that is marked as classified but is being transported to an unapproved destination. Information flow control policies and enforcement mechanisms are commonly employed by organizations to control the flow of information between designated sources and destinations (e.g., networks, individuals, devices) within information systems and between interconnected systems. Flow control is based on the characteristics of the information and/or the information path. Application-specific examples of flow control enforcement can be found in information protection software (e.g., guards, proxies, gateways, and cross domain solutions) employing rule sets or establishing configuration settings restricting information system services or providing message-filtering capability based on content (e.g., using key word searches or document characteristics). Applications providing information flow control must be able to enforce approved authorizations for controlling the flow of information between interconnected systems in accordance with applicable policy. SharePoint Central Administrator is a powerful management tool used to administer the farm. This server should be installed on a trusted network segment. This server should be used to run required services rather than user-oriented web applications.

Applications providing flow control must identify data type, specification, and usage when transferring information between different security domains so policy restrictions may be applied. A security domain is defined as a domain implementing a security policy and administered by a single authority. Data type, specification, and usage includes using file naming to reflect the type of data being transferred and limiting data transfer based on file type.

Applications are required to display an approved system use notification message or banner before granting access to the system providing privacy and security notices consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance and stating that: (i) users are accessing a U.S. Government information system; (ii) system usage may be monitored, recorded, and subject to audit; (iii) unauthorized use of the system is prohibited and subject to criminal and civil penalties; and (iv) the use of the system indicates consent to monitoring and recording. System use notification messages can be implemented in the form of warning banners displayed when individuals log on to the information system. System use notification is intended only for information system access including an interactive logon interface with a human user and is not intended to require notification when an interactive interface does not exist. Use this banner for desktops, laptops, and other devices accommodating banners of 1300 characters. The banner shall be implemented as a click-through banner at logon (to the extent permitted by the operating system), meaning it prevents further activity on the information system unless and until the user executes a positive action to manifest agreement by clicking on a box indicating "OK".

Audit records can be generated from various components within the information system, such as network interfaces, hard disks, modems, etc. From an application perspective, certain specific application functionalities may be audited as well. The list of audited events is the set of events for which audits are to be generated. This set of events is typically a subset of the list of all events for which the system is capable of generating audit records (i.e., auditable events, time stamps, source and destination addresses, user/process identifiers, event descriptions, success/fail indications, filenames involved, and access control or flow control rules invoked). Organizations may define the organizational personnel accountable for determining which application components shall provide auditable events.

It is critical when a system is at risk of failing to process audit logs as required; actions are automatically taken to mitigate the failure or risk of failure. One method used to thwart the auditing system is for an attacker to attempt to overwhelm the auditing system with large amounts of irrelevant data. The end result is audit logs that are either overwritten and activity thereby erased or disk space that is exhausted and any future activity is no longer logged. In many system configurations, the disk space allocated to the auditing system is separate from the disks allocated for the operating system; therefore, this may not result in a system outage.

Decisions regarding the utilization of mobile code within organizational information systems need to include evaluations that help determine the potential for the code to cause damage to the system if used maliciously. Mobile code technologies include, for example, Java, JavaScript, ActiveX, PDF, Postscript, Shockwave movies, Flash animations, and VBScript. Usage restrictions and implementation guidance apply to both the selection and use of mobile code installed on organizational servers and mobile code downloaded and executed on individual workstations. Applications can prevent the execution of prohibited mobile code by leveraging architectures that provide a virtual execution environment sometimes referred to as a "sandbox". The mobile code is executed within this isolated environment apart from the host's indigenous operating environment that allows for mobile code capability restrictions and helps to prevent malicious code from accessing system resources and data. Policy and procedures related to mobile code address preventing the introduction of unacceptable mobile code within the information system. The DoDI 8552.01 policy pertains to the use of mobile code technologies within DoD information systems. The application must prevent the execution of prohibited mobile code.

This requirement focuses on communications protection at the application session, versus network packet level. Session IDs are tokens generated by web applications to uniquely identify an application user's session. Applications will make application decisions and execute business logic based on the session ID. Unique session identifiers or IDs are the opposite of sequentially generated session IDs that can be easily guessed by an attacker. Unique session IDs help to reduce predictability of said identifiers. Unique session IDs address man-in-the-middle attacks, including session hijacking or insertion of false information into a session. If the attacker is unable to identify or guess the session information related to pending application traffic, they will have more difficulty in hijacking the session or otherwise manipulating valid sessions. When a user logs off, or when any other session termination event occurs, the application must terminate the user session to minimize the potential for an attacker to hijack that particular user session.

The information system isolates security functions from nonsecurity functions by means of an isolation boundary (implemented via partitions and domains) controlling access to, and protecting the integrity of, the hardware, software, and firmware that perform those security functions. The information system maintains a separate execution domain (e.g., address space) for each executing process.

Preventing the disclosure of transmitted information requires that applications take measures to employ some form of cryptographic mechanism in order to protect the information during transmission. This is usually achieved through the use of Transport Layer Security (TLS), SSL VPN, or IPSEC tunnel. Alternative physical protection measures include Protected Distribution Systems (PDS). PDS are used to transmit unencrypted classified NSI through an area of lesser classification or control. Inasmuch as the classified NSI is unencrypted, the PDS must provide adequate electrical, electromagnetic, and physical safeguards to deter exploitation. Refer to NSTSSI No. 7003 for additional details on a PDS.

Separation of duties is a prevalent Information Technology control implemented at different layers of the information system including the operating system and in applications. It serves to eliminate or reduce the possibility that a single user may carry out a prohibited action. Separation of duties requires the person accountable for approving an action not be the same person who is tasked with implementing the action. This requirement is intended to limit exposure due to user accounts being used to operate from within a privileged account or role. Limiting the access and permissions of privileged accounts to the minimum required, reduces exposure if the account is compromised and provides forensic history of activity when operating from these accounts. This policy limits the Farm Account privileges in AD. However, default permissions for this account are configured by the SharePoint Products Configuration Wizard during product installation.

Web Part galleries are groupings of Web Parts. There are four Web Part galleries: Closed Web Parts, Site Name Gallery, Server Gallery, and Online Gallery. The Online Gallery is a collection of Microsoft MSNBC Web Parts located on the Internet. Allowing users to access the Online Web Part Gallery causes a significant performance hit on the server, due to the server attempting to connect to the MSNBC online gallery. This could result in a Denial-of-Service. The Online Gallery could contain Web Parts from unknown third parties, which could increase the risk of a malicious code execution attack. Preventing users from accessing the Online Web Part Gallery decreases the system's attack surface.

Separation of duties is a prevalent Information Technology control implemented at different layers of the information system including the operating system and in applications. It serves to eliminate or reduce the possibility that a single user may carry out a prohibited action. Separation of duties requires the person accountable for approving an action not be the same person who is tasked with implementing the action. This requirement is intended to limit exposure due to user accounts being used to operate from within a privileged account or role. Limiting the access and permissions of privileged accounts to the minimum required, reduces exposure if the account is compromised and provides forensic history of activity when operating from these accounts. This policy limits the Farm Account privileges in AD. However, default permissions for this account are configured by the SharePoint Products Configuration Wizard during product installation. This account is referred to during the installation as the “Database Access” account. By default, the account is used as the service account for the SharePoint Timer Service and the SharePoint Central Administration Web Site Application Pool. These settings should not be changed. Furthermore, this account should not be used as the service account for non-privileged services, applications, or application pools.

When data is exchanged between information systems, the security attributes associated with said data need to be maintained. Security attributes are an abstraction representing the basic properties or characteristics of an entity with respect to safeguarding information, typically associated with internal data structures (e.g., records, buffers, files) within the information system and used to enable the implementation of access control and flow control policies, reflect special dissemination, handling or distribution instructions, or support other aspects of the information security policy. Security attributes may be explicitly or implicitly associated with the information contained within the information system.

Note: If no data is exchanged between systems, and has been documented by the Data Owner, IRM is not required. This requirement is Not Applicable. Review the SharePoint server configuration to ensure the integrity of security attributes exchanged between systems is validated. An IRM must be enabled in SharePoint. The Windows Rights Management Services (RMS) (or a comparable IRM product) can either be located through Active Directory or specified. In Central Administration, click Security. On the Security page, in the Information policy list, click "Configure information rights management". If "Do not use IRM on this server" is selected, or if a configuration error message is displayed (such as "... IRM will not work until the client is configured properly"), this is a finding.
